Discuss how the amphipathic structure of a phospholipid allows it to spontaneously form lipid bilayers.

What is meant by lipid bilayers of platelets cells having a “sidedness” to them? Another way...

What is meant by lipid bilayers of platelets cells having a “sidedness” to them? Another way of stating this, is how do the inner and out leaflets compare to each other in the composition of the lipids and proteins 2. Blood clotting factors are found circulating in the blood. Why are they not constantly causing blood clots? Phosphatidylserine (PS) provides the most active catalytic surface for forming coagulation factor complexes. PS is generally located on the cytoplasmic surface of blood...

What is a property of phospholipids that explains why lipids self-assemble into a bilayer?

Phospholipids have the ability to spontaneously form complex structures such as lipid bilayers. What is a property of phospholipids that explains why lipids self-assemble into a bilayer? Lipids assemble the membrane around a protein scaffold, which then dissociates The hydrophobic tails of lipids covalently bond with one another within the membrane. Opposite charges on the heads and tails of lipids cause them to be attracted to one another. The hydrophilic heads of lipids are exposed to water at the membrane's surface. Proteins help lipids form long...

1. Discuss how and why a plasma membrane lipid bilayer is fluid and what types of physical properties of the lipids contribute to the fluidity of the membrane. This should include a discussion of the different types of fatty acids and other lipids and environmental interactions that can change fluidity.
